The tests shown below were
performed in IBM's Hudson Valley Acoustics Lab in Poughkeepsie, NY on April 19, 2004.

Note the large, motorized boom stand that supports the test
microphone. Each product is tested 100 times - automated, of course! - while the
microphone moves around the room in all three planes. Then all of the test results are
averaged together so no one location in the room dominates the results.
